This invention relates generally to electrical `devices for lighting Vcigars or cigarettes.

It is an object of this invention to devise a cigar lighter Which will be simple in construction and convenient to operate.

It is a further object of this'invention to provide an improved form of heating unit which may be readily removed from a cigar lighter for replacement. y

It is a further object of this invention to simplify and improve the mounting for the control switch of a cigar lighter and to facilitate insulating the same.

It is a further object of this invention to devise a single insulating member for mounting both the control switch elements and the heating elementof a cigar lighter.

Further objects of this inventionvill appear from the following description l in which We have set forth the preferred embodiment of our invention.. Tt is to be understood that the scope of the invention is to be determined from' the appended claims and the state of the prior art.

Referring to the drawings: A' Figure 1 is a cross sectional elevational view of a cigar lighter constructed in accordance With this invention.

Fig. 2 is a transverse cross sectional View taken along the line 2-2 of Fig. 1. 1

Fig. 3 is a cross sectional view taken along the line 3-8 of Fig. 1. l

Fig. 4 is a cross sectional vieW taken along the line t-a ofFigl. y

Fig. 5 is a cross sectional view taken along the line 5-5 of Fig. 1.

F ig. 6 is a diagrammatic view illustrating the manner in which the resistance Wires are connected to the heating unit terminals.

Fig. 7 is a cross sectional view taken along the line 7-7 of Fig. 2.

The invention comprises generally a'body member 10 upon the; upper endof Which is mounted a heating element 11. The body member has been shown as comprising a lower flanged base portion 12 and an upper cup-shaped shell 13,- the base portion being connected to the shell by means of'a hollow stem portion 14. fWhile it is Obvious that these parts may be made partially or entirely integral, they are preferably constructed as separate elements and perma nently secured together during the process of manufacture. Thus forexample, the base portion 12 and shell 13 may be constructed of pressed sheet metal While the stem por-` tion la may be formed of tubular material.

The upper and lower ends of the stem pore` tion are provided with rolled over portions` 16 and 17 for engagingthe adjacent ends of the shell 13 and base portion 12 respectively. 4

Inv order to mount the heating unit 111 upon the cup-shaped shell 13' there is provided a dise 19 of suitable insulating mate` rial such as. mica, which has its periphery secured to the upper lrim of the cup 13. The heating element is preferably mounted centraliy of this disc 194 so that the disc forms a shelf surrounding the element. 'As the diameter of the shell 13 is substantially larger than the diameter of the heating element 11 thisshelf will prevent the heating element from coming into direct contact With a supporting surface in case .the lighteris tipped' over on one side, and forms aconvenient means for ,catching ashes which may drop `from the heating element When the lighter is in use. .t v i v l l The heating element 11 has been constructed so that it may be removed from thelighter as a unit Without the necessity of disconnecting Wires or removing screws or bolts. Thus this element hasbeenvshown as comprising a core 20oflsuitable refractory material'having the intermediate portion of its periphery grooved to receive a suitable resistance Wire 4 preferably coiled so as to increase its length and `effective resistance. AIn order to minimize direct transfer of heat from the re sistance Wire to the coreby yconvection and 21. This resistance Wire: is

thus permit the Wire to rapidly attain a glowing,temperature, the core is preferablyprovided ywith a pluralityl of longitudinal. grooves 22 so that the resistance. Wire con'- tacts with the core only. at spaced points about the core periphery. One end of the core isprovided With an extension 23 Which f ductors are connected to the strips 53 land 58V whereby the switch comprising the movable strip 57 and the stationary contactl 61, is placed in series with the heating element. Therefore upon closing this switch by pushing the button 60 the resistance wire is quickly heated to incandescence to light a cigar or cigarette. For convenience the other'ends of the conductors may be provided with a suitable electrical plug' 65 for attachment to any standard socket or receptacle.

Because the shell 13 together' with the disc 19 forms a shelf surrounding the lower portion of the heating element, there is no danger of starting a fire in case thelighter becomes upset after it has been in use. For

example, the dot and dash line 7l indicates the position which the lighter would take in upset rposition with respect to a plane supporting surface, thus showing that lin this upset position the heating element would be a substantial distance away from any inflammablematerial. The switch also opens itself upon release of the push `button so that there is no possibility of the device lterial 74.

remaining connected to the line after being in use." To aid in retaining the device in upright positionthe base portion 12 has been shown provided with a weight in the form of a 'washer 72 which is'retained within the base by means of a rolled edge portion 73. The lower faceof this washer is covered overby means of a suitable cushioning malVe claim l. In cigar lighter, a heatingk element comprising a refractory core, a resistance wire wound upon said core, and means for mounting the core and making electrical connections tothe resistance wire comprising a metal sleeve secured to one end of the core, a bolt extending centrally through the `core' and serving to retain the sleeve upon the core, and means for electrically connectsaid sleeve and bolt to the ends of said resistance wire.

2. in a lighter of the class described, an elongated refractory core having parallel ribs spaced circumferentially about its periphery, a resistance wire wound upon said core, a cylindrical metal guard surrounding` said core and wire and mounted uponthe core, said guard having side walls lying adjacent to .but spaced from said wires, said guard having. its side walls perforated whereby air drawn thru any side of the,A

guard will be heated by'contact with` said core vand wire. 1
